, This invention relates to an improved construct'ion of ophthalmicmounting; and has for its object to provide in such a mounting a pair ofspaced metal eyewiressecured in posi- 5 tion by a bridge-bar, each ofthe eyewires being covered by a non-metallic rim having a perlpheralopenlng or pierclng of a size to receive and be threaded on to anunattached v end of the bridge-bar prior to the soldering of. this endof the bridge-bar to its eyewire,

thefirst rim after having been threaded onto the bar being atoncepositioned on its wire and the second rim'threaded onto the bar 7being attached to its'leyewire after the free end of the bridge has beensoldered to its eyewire. i

' With these and other objects in'view, the

' invention consists of certain novel features scribed, and particularlypointed out in the of construction, as will be more fully deappendedclaims.

I then slidethe rim along thebridge and snap it into itspermanent position over itseyewirei'i In some instances, I provide end pieces 15 on the metaleyewires and in this case I slot the non-metallic'rim as at 16 toreceive these end pieces.

5 By my improved construction, I am enabled to very readily position thenon-metal lic rims over the metallic eyewires and pro vide the minimumamount of an opening forthe reception of the bridge-bar which extendstherethrough to be attached to the metallic eyewires within the rims.

The foregoing description is directed solely towards the constructionillustrated, but I desire it to be understood that I reserve theprivilege of resorting to all the mechanical changes to which the deviceis susceptible, the invention being defined and limited only by theterms of the appended claims.

7 I claim:

2o 1. A method of applying non-metallic rims to the metallic eyewires ofan ophthalmic mounting, which consists in attaching one end of thebridge-bar to one ofthe eyewires, piercing the non-metallic rims with ahole of a size to receive the bridge member, threading V the firstnon-metallic rim onto the bridge-bar and snapping it into position overits eyewire, threading the second non-metallic rim onto the free end ofthe bridge-bar then soldering the free end of the bridge-bar to itseyewire,

' and subsequently sliding the second rim along the bridge-bar andsnapping it in position over its eyewire. 1

2. Anophthalmic mounting having a pair of spaced metal eyewires, abridgebar soldered at its ends to said eyewires tosecure themtogether,and a U-shaped non-metallic rim for each eyewire having anopening intermediate its edges, the bridge-bar extending 40 through theopenings in said rims and covering the soldered joint at each ofthe endsof said bridge-bar.

3. An ophthalmic'mounting having a pair I of spaced metal eyewireshaving end pieces, a p bridge-bar soldered at-its ends to said eye- 1wires to secure them together, and a U-shapednon-metallic rim for eacheyewire having an opening intermediate its edges, the bridge Y barextending through the openings in saidrims and covering the solderedjoint at each r of the ends of said bridge-bar, the ends of eachnon-metallic rim being formed to re ceive its respectiveend piece. c .7

In testimony whereof I afliX my signature.
